A linkage device includes a drive component and a support member. The drive component is rotatable during a transmission stroke and an idle stroke. The support member is coupled to the drive component. The drive component and the support member rotate synchronously during the transmission stroke. At least a part of the drive component idles with respect to the support member during the idle stroke. The support member has a retracted position and a support position switched by the transmission stroke. The support member in the retracted position is suitable for storage. The support member in the support position is suitable for stopping and limiting.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The linkage device according to claim 1, further comprising an overturning member coupled to the first shaft, wherein the overturning member is configured to drive the first shaft to reciprocally rotate, and in the support position, the support member stops and limits the overturning member.
3. The linkage device according to claim 1, wherein the support member extends in a same direction as the second shaft in the retracted position, and the support member extends at an angle to the second shaft in the support position.
11. The linkage device according to claim 10, wherein the second gear comprises a first segment and a second segment in an axial direction; the incomplete gear transmissively meshes with the first segment; and the first gear transmissively meshes with the second segment.
15. The linkage device according to claim 12, wherein the fixed portion comprises a first stopping portion, and the first shaft comprises a second stopping portion, the first stopping portion being fitted with and stopped by the second stopping portion to limit a rotation stroke of the first shaft.
